ALEXANDER WINSTON, OF FAYETTE, IOWA, ASSIGNOR OF TWO-THIRDS HIS RIGHT TO OLIVER A. DAUD, OF SAME PLACE.

IMPROVEMENT IN DRAFT-EQUALIZERS.

Specification forming part of Letters Patent No. 206,696. dated August 6, 1878 application filed July 2, 1878.

To all whom it may concern.-

Be it known that I, ALEXANDER WIN- STON, of Fayette, in the county of Fayette and State of Iowa, have invented certain new and useful Improvements in Equalizing Attacbments for Whiffletrees and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enableothers skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawing, and to the letters of reference marked thereon, which form a part of this specification.

This invention consists in an improved sliding bar and draft-equalizing attachments for whiflletrees and double-trees, which will be hereinafter fully set forth.

In the drawings, Figure l is a plan of a wagon-tongue and double-tree with my improvements applied thereto. Fig. 2 is a vertical longitudinal section. Fig. 3 shows the retaining-strap, and Fig. 4 is the brace for holding the tongue and cross-head.

a is the tongue, having the cross-head a, and a is the brace, which is applied thereto as shown. bis the double-tree, held to the tongue by the bolt or hammer b and hammerstrap b 0 c are the whiffletrees.

d is a bifurcated bar, united, by preference, to the rear end of the hammer-strap b It has its ends bent down and under, so as to form the guide-loops d d, in which the equalizing-bar slides, and the flanges d bent downward, so as to provide suitable meanswhereby it is secured to the cross-head a, as shown in Fig. 2.

e is the equalizing-bar, composed of the slidebar 0 and the supportingbar e united as shown, and has formed on its ends the hooks or eyes a. It is placed between the bar (I and the tongue (1, and is pivoted on a pin, 0, which passes through the bar d and the center of the supporting-bar 0 into the said tongue.

The curved slidin bar 0 slides back and forth in the loops d d. It is provided with a stop, 0 arranged centrally on its upper side, which stop moves between the arms (I of the bar (1, and thereby limits the play of said equalizing-bar.

ff are the stay-rods which connect the ends of the equalizing-bar e with the bolt 0 of the whiffietrees c, as shown.

The bar 6, having its center of motion on the pin a, in front of the line of movement of the sliding bar 6, serves as a draft-equalizer between the ends of the whiflietree. The stop 0 checks the rear movement of any given side or end of the whiffletree, and prevents the latter from striking against the wheel.

Having described my invention, what I claim, and desire to secure by Letters Patent, is-

1. In combination with the double-tree b and tongue (1, the rocking equalizing-bar 0, having hooks or eyes 0, and pivoted to the said tongue in rear of said double-tree, and rods], arranged to operate substantially as and for the purposes set forth.

2. The bifurcated bar (I, having the loops (1 and flanges (1 in combination with the rocking bar 0, composed of the supporting-arms c and sliding bar 6, having stop 0 and hooks or eyes 0 rodsf, double-tree b, and tongue a, substantially as and for the purposes set forth.

In testimony that I claim the foregoing as my own I aflix my signature in presence of two witnesses.

ALEXANDER \VINSTON.
